Abstract
The aim of this pilot study was to determine perceived efficacy of center-based sensory processing groups among caregivers of children receiving early intervention services. Using a test–retest design, 10 caregivers and their children participated in an 8-session playgroup. The findings indicated that the caregivers' perception related to their understanding of sensory processing principles and the efficacy of sensory processing activities increased. Limited statistical significance was found; however, medium and large effect sizes were demonstrated. Furthermore, the caregivers' perceptions of their child's response to sensory stimuli remained unchanged. Further research is warranted regarding the efficacy of center-based group interventions among early intervention populations.
